Abstract

U sklopu istraživanja IRI 2 projekta pod nazivom Razvoj dizalice topline zrak voda s prirodnom radnom tvari i naprednim sustavom odleđivanja isparivača (KK.01.2.1.02.0132), sufinanciranog sredstvima iz Europskog fonda za regionalni razvoj, ERDF, instalirana je prototipna dizalica topline u sjevernu zgradu Fakulteta strojarstva i brodogradnje, Sveučilišta u Zagrebu.
Navedena dizalica projektirana je za kondicioniranje fakultetskog prostora površine 200 m2, čime je osigurano ispitivanje dizalice topline u relevantnom okruženju. Ispitna linija opremljena je brojnim senzorima i upravljačkom opremom za što točnije i bolje praćenje parametara procesa. Eksperimentalnim mjerenjem nekoliko uzastopnih dana prikupljeni su brojni podaci te su na temelju toga izneseni bitni parametri za praćenje rada dizalice topline. Prikupljeni podaci svrstani su u kategorije, obrađeni te grafički prikazani za bolje praćenje parametara u radu.
Budući da je Sjeverna zgrada u međuvremenu obnovljena, a Fakultet zajedno sa dizalicom izmješten, bilo je potrebno provesti ponovni proračun projektnog toplinskog opterećenja prema normi HRN EN 12831 i proračun rashladnog opterećenja prema normi VDI 2078. Proračun je proveden u programu IntegraCad. Novo projektno toplinsko opterećenje iznosi 15,1 kW, dok je za sezonu hlađenja rashladno opterećenje 12,6 kW.

Abstract (english)

As part of the research of the IRI 2 project entitled Development of an air-water heat pump with a natural working substance and an advanced evaporator system (KK.01.2.1.02.0132), co-financed by funds from the European Regional Development Fund, ERDF, a prototype heat pump was installed in one of the buildings at the Faculty of Mechanical Engineering and Naval ArhitectureZagreb, Univesity of Zagreb.
This heat pump was designed to condition the faculty area of 200 m2, which ensured the testing of the heat pump in the relevant environment. The test setup is equipped with numerous sensors and control system for the most accurate and better parametar monitoring. Numerous data collected through experimental measurements over several consecutive days were processed nad presented, with essential parametars for monitoring the heat pump's operation highlighted. The collected data were categorized, processed and graphically displayed for better monitoring parameters of operation.
Following the renovation of North building and relocation of the Faculty, it was necessary to recalculate the heat load according to the HRN EN 12831 standard and the cooling load according to the VDI 2078 standard. The calculation was executed in the IntegraCad. The new calculated heat load is 15,1 kW, while the cooling season requires 12,6 kW.
